Due to the nature of the drive recorder, it is desirable that the imaging direction be a direction in which the outside of the vehicle can be imaged. Further, the switching of the image capturing direction (S101) can be omitted, and when omitted, the image capturing direction at the time of system startup remains the same. Information on the angle difference θ between the image pickup direction of the camera 1 and the front direction θ 0 and the occupant position acquired by the occupant position detection unit 8 is provided to the camera control unit 3.
(S102), the image pickup by the camera 1 is started (S102).
103), the image of the camera 1 is recorded in the temporarily recorded image section 4 (S104). When the acceleration sensor 9, the airbag sensor 10, and the vehicle speed sensor 11 detect the occurrence of an accident (S105), the imaging direction of the camera 1 is switched to the driver's seat direction (S106).

106) as the driver's seat direction, but the occupant position direction information 18
Based on the above, the image information can be transmitted to the center for other passengers in the same manner as in the driver's seat. Switching of the image capturing direction of the camera 1 in this case is performed by switching the angle difference between the position information held in the occupant position direction information 18 and the current image capturing direction by the drive unit 2 as in the case of switching to the driver's seat. realizable. In this case, for example, a method may be considered in which the imaging direction of the camera 1 is sequentially switched to the occupant position based on the occupant position direction information 18 at predetermined time intervals and transmitted to the center.
